Objective: To determine the association of Diastolic dysfunction in patients with atrial fibrillation after CABG surgery.
Methodology: This cross sectional study was conducted from 01st May, 2022 to 30th Nov, 2022 in department of Cardio-thoracic Anaesthesia and Adult Cardiac Critical care, AFIC/NIHD, Rawalpindi. 154 patients were assessed for preoperative diastolic dysfunction, and grade. After CABG, they were monitored for 24 hours in ICU for atrial fibrillation (AF). If there was AF, it was noted down.
Results: Most of our patients were male (81.2%). Mean age of patients was 58.69 ±8.25 years. Hypertension was present in 71.4% patients. Mean ejection fraction was 49.88±6.28%. Grade I diastolic dysfunction was present in 42.9% patients. Frequency of AF was 31.2%. Frequency of diastolic dysfunction (Grade 1 & 2) was higher in non-AFib group while Grade-3 dysfunction was higher in AFib group and the association was statistically significant (p<0.01). Mean difference of ejection fraction and hypertension status was also significantly associated with AFib status with p-values (p=0.007 and 0.034 respectively). All rest variables had insignificant findings with regard to AFib status (p>0.05).
Conclusion: Our study shows that grade III diastolic dysfunction is associated with increased frequency of post-operative
atrial fibrillation.
